Benefits of technology

[0006]An object of the present invention is to overcome the shortcomings of the prior art by providing a simple and effective three-dimensional (3D) color display system using a color separation strategy, and a backlight for a liquid-crystal display (LCD) panel in such a 3D color display system.

Problems solved by technology

However, the market share of projector-based systems in the home-theater category is in decline.
Unfortunately, such an LCD panel comprising right-eye RGB pixels and left-eye RGB pixels is difficult and expensive to manufacture.
Unfortunately, such an LCD panel comprising R, G / Y, and B subpixels is difficult and expensive to manufacture.

Embodiment Construction

[0031]With reference to FIG. 1, the present invention provides a three-dimensional (3D) color display system 100 using a color separation strategy, for application in home theaters, video game systems, and the like. The 3D color display system 100 comprises a 3D color display 110 for displaying spectrally distinct right-eye and left-eye images in alternation, which are viewed using 3D color eyeglasses 120.

[0032]Advantageously, the 3D color display 110 is also capable of functioning as a two-dimensional (2D) color display, without making any physical changes to the 3D color display 110. Use of the 3D color eyeglasses 120 is unnecessary when the 3D color display 110 functions as a 2D color display.

[0033]The 3D color display 110 is a flat-panel liquid-crystal display (LCD). Preferably, the 3D color display 110 is an active-matrix LCD, such as a thin-film transistor (TFT) LCD. The 3D color display 110 may be a twisted nematic (TN) LCD, an in-plane switching (IPS) LCD, a vertically align...

Abstract

The present invention provides a three-dimensional (3D) color display system, and a backlight for a liquid-crystal display (LCD) panel in such a 3D color display system. The backlight comprises a right-eye backlight module, a left-eye backlight module, and a backlight control module. The right-eye backlight module transmits a right-eye first-color band, a right-eye second-color band, and a right-eye third-color band, from which right-eye images are produced, to the LCD panel. The left-eye backlight module transmits a left-eye first-color band, a left-eye second-color band, and a left-eye third-color band, from which left-eye images are produced, to the LCD panel. The backlight control module activates the right-eye backlight module during right-eye activation intervals and the left-eye backlight module during left-eye activation intervals, the right-eye activation intervals and the left-eye activation intervals alternating at a switching rate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present invention claims priority from U.S. Provisional Patent Application No. 61 / 209,308 to Ockenfuss, filed on Mar. 4, 2009, which is incorporated herein by reference.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates to a three-dimensional (3D) color display system and, in particular, to a backlight for a liquid-crystal display (LCD) panel in a 3D color display system.BACKGROUND OF THE INVENTION[0003]Three-dimensional (3D) color display systems use a variety of strategies to produce distinct images for a viewer's right eye and left eye. Among the most widespread 3D color display systems are projector-based systems using a color separation strategy to produce spectrally distinct right-eye and left-eye images, which are viewed with passive color-filter eyeglasses, as disclosed in U.S. Pat. No. 6,698,890 to Jorke, issued on Mar. 2, 2004, and in U.S. Pat. No. 6,687,003 to Sorensen, et al., issued on Feb. 3, 2004, which...
